Description
The AT60142F/FT are very low power CMOS static RAM organized as 524 288 x 8
bits.
Atmel brings the solution to applications where fast computing is as mandatory as low
consumption, such as aerospace electronics, portable instruments, or embarked
systems.
Utilizing an array of six transistors (6T) memory cells, the AT60142F/FT combine an
extremely low standby supply current (Typical value = 1 mA) with a fast access time at
15 ns over the full military temperature range. The high stability of the 6T cell provides
excellent protection against soft errors due to noise.
The F version is biased at 3.3 V and is not 5V tolerant: it is available to 15 ns
specification.
The FT version is a variant allowing for 5V tolerance: it is available in 17 ns
specification.
The AT60142F/FT are processed according to the methods of the latest revision of the
MIL PRF 38535 or ESCC 9000.
It is produced on a radiation hardened 0.25 µm CMOS process.
